Abstract

The CDF and D0 experiments finalize the analysis of their full statistics collected in the $p \bar p$ collisions at a center-of-mass energy of $\sqrt{s} = 1.96$ TeV at the Fermilab Tevatron collider. This paper presents several new results on the properties of hadrons containing heavy $b$- and $c$-quarks obtained by both collaborations. These results include the search for the rare decays $B^0, B^0_s \to \mu^+ \mu^-$ (CDF), the study of CP asymmetry in $B_s \to J\psi \phi$ decay (CDF, D0), the measurement of the like-sign dimuon charge asymmetry (D0), the measurement of CP asymmetry in $D^0 \to K^+K^-$ and $D^0 \to \pi^+\pi^-$ decays (CDF), and the new measurement of the $B_s \to D_s^{(*)+} D_s^{(*)-}$ branching fraction (CDF). Both experiments still expect to produce more results on the properties of heavy flavours.
